<title>VeraCrypt - Free Open source disk encryption with strong security for the Paranoid</title>
<meta name="description" content="VeraCrypt is free open-source disk encryption software for Windows, Mac OS X and Linux. In case an attacker forces you to reveal the password, VeraCrypt provides plausible deniability. In contrast to file encryption, data encryption performed by VeraCrypt is real-time (on-the-fly), automatic, transparent, needs very little memory, and does not involve temporary unencrypted files."/>

<h1>Key Derivation Algorithms</h1>

<div style="text-align:left; margin-top:19px; margin-bottom:19px; padding-top:0px; padding-bottom:0px">
A key derivation function (KDF) transforms your password (and optional keyfiles) into cryptographic keys used to decrypt a VeraCrypt volume header. KDFs slow down brute-force attacks and protect against precomputation by incorporating a large random salt and a tunable work factor (e.g., iterations, memory).

<strong><a href="Argon2id.html" style="color:#0080c0; text-decoration:none">Argon2id</a>:</strong> A modern, memory-hard KDF (based on BLAKE2b internally). Recommended for new volumes. No separate hash selection is required.
